It sounds like from the information provided that Kerr and Embley had a serious biff - Embley being the aggressor. The Police were called to scene.
Embley is looking like he is in trouble but Police can't press charges unless Kerr agrees to them. Kerr doesn't want to go down this path so decides that the best thing to do for himself and the club is to pretend it never happened.
West Coast are of course happy about this and will pretend it was just mucking around. They are already in enough crap to go to the hangman so are very eager to pretend its nothing.
